a new study shows how alzhiemer's takes a tremendous toll on the people who care for its victims, we told you about this earlier this week. according to the study care takers sacrifice physical and financial wellbeing, hast the people that care for alzhiemer's cut back on their own expenses in order to do so. 28% of them eat less for go

hungry. 20% sacrifice they are mental health. the information is included in the alzheimer's's association 2016 alzhiemer's disease facts and figures. joining us now is dr keith fargo, the director of scientific programs and outreach. >> good to have you with us. these numbers and the stories of suffering are really stark and heart wrenching. things are going to get worse as baby-boomers get over. >> that's right. that's what we expect. you are right. the numbers are sobering. this disease takes a toll on family members, not just the person that has the disease, but the people who are taking care of them. and what they found is that this financial toll, not just the hours and the emotional toll that it stakes, the financial toll is larger than people expected. i mean, you mentioned some of

the numbers. people are cutting back on medical care to take care of their loved one, many are struggling with feeding their family appropriately because of the added expenses that they were taking on. and this is a really difficult thing for people to deal with, and most people are not prepared for the added expenses of having someone in your family have dementia. >> they race the question of whether there's a failure of not paying enough attention for those that care for those that have alzhiemer's. >> they raise the question. there are things that people can do to get ready for this added responsibility. and one of those things is to get educated. there are programs and services available to people. one of the people found were not aware of what programme was

available or what they could pay for. a third of the people in the survey did not know where the medicare would pay for long-term care or nursing home care. a third believed it wood. a third of the people understood that it did not pay. they cost on average 80,000 to 90,000. you end up with the families side striped and taken by surprise. >> most struggled to pay regular policies. getting a policy covering nursing home care is tough to afford. it would be. alzhiemer's is an expensive disease and change to society when you factor in medicare and

medicaid. in the united states it cost 236 billion this year and that's no different when you are looking at society-wide impact verses looking at the individual. most are not ready to pay that money. or pay for expensive insurance policies. is enough being done. the alzheimer's brought together a group of scientists and we asked what kind of investment would it take to find an effective treatment by the year 2025. and with that group of scientists, they told us it would take an investment of

200,000 each year. it was wonderful news it left than half of what scientists tell us is needed. thank you, good of you to join us. thank you. a national effort to the narrow the divide is taking place. 100 apartments have superfast and free internet connections. >> reporter: up until last month this family had no computer or internet access. >> i had no idea that it was that much more out there. being on the phone was one thing, being on a computer is different. it's a lot faster. today she is online.
